FILLING DETECTOR.

operation of the device which removes empty bobbins from the loom andreplaces or replenishes same with full bobhins.

.A further object of the invention is to provide simple, and economicalmeansV for effecting electrical operation of the bobbin and.replenishing device, eiliciently and with certainty.

In the drawings Figure 1, is a top plan View of the invention;

Figure 2 is a section on line 2 2 of Fig. 1

`.Figure 3 is a side elevation of Fig. 1 and Figure Llc and Fig. 5 arefragmentary views of two ditl'erent forms of bobbins employed inconnection with the invention.

In proceeding in accordance with the present invention, a bracket l, isemployed, which is bolted at 2 to the frame 2`',.of the bobbin removingand replenishing device, the latter generally designated el. y rlihebracket is provided with a slotted guide i3, in which a slide t5, formedof insulatinpl material is movable. The forward end of the slide isprovided with a pair. of metal points 7, which are mounted in' longit-irdinal bores formed in the slide. The points 7, have rods 8, connectedthereto, the rear ends of which rods have metal contacts 9, securedthereto. Springs 10, surround the rods 8, and normally urge the pointsi', forwardly of the slide.

The rear end of the slide is cutaway to accommodate the contacts,whereby the upper faces of the contacts 9 project above the upper faceof the slide, although same may be Hush therewith, if desired.

A spring tensioned rod 1.2, is slidably carried by a guide 13, at therear of the bracket 1, and has its forward end connected to the rear endof the slide so as to normally urge the latter outwardly. Adjustablenuts 14, on the rear end of the rod, abut the i Application filed May 29rugated as shown at 25.

guide 13, and control fthe extent of `forward movement of the rod.

An electric coil 15, is mounted on the` bracket `in opposed 'relation toan armature 16, the latter having a stem-.17, slidable Ain guide 13, andtensioned by a coilspring 1S; An L-shaped finger 19, is carried by thestem 17, and is held thereon by and betveen nuts 20. ,A pair of springfingers 21, are carriedby the bracket and Vhave wiping contact with thecontacts 9. Wires 22 and 23, lead from any 'suitable source ofelectrical supply, not shown, to the coil.

' The bobbins A and B are provided with metallic ferrules, preferablycopper, which may be either plain as shown at 24, or cor- In theinstance of the plain ferrule, the bunch must he huilt on the bobhin toallow suflicient leeway for the shuttle to crossthe shed. ln theinstance of the corrugated ferrule, su'ticient yarn, during buildin@ orspinning is laid in the dwells of the corrugations to take the place ofthe bunch.

The rod 12, has an arm 26,'rigidly connected thereto adapted to beoperated `by a. withdrawing arm or member 27, of the loom, while thelinger 19 is perforated and receives therethrough, a pin 28, whichlatter operates the bobbin removing and replenish` ing device 1.

ln operation, it will be understood that so long as the bohbin hassutiicient ylayers of yarn thereon 'to prevent engagement of the points7, with` the copper ferrule of the bohbin, the bobhin removing andreplenishingzj device will be inactive. Upon en'iptying of the hobbinthe contact points 7, will engage the copper ferrule of the bobbin and`comu plete an electrical circuit through the coil 1.5, energizing thelatter and thereby attracting the. armature 16. The armature 1G willthus he slid to the right of the dra vings, causing its stem 1.7, tomove the inger 19, to the right, thereby actuating the pin 28, andrendering the bobbin removing and replenishing device active, to removethe empty bobbin and supply a fresh bobhin to the loom. Immediatelyfollowing closing4 of the circuit, as described, the arm 27 will enterinto action and engaging the arm 26, will move the latter and therewith`the insulating slide 6, to the left of the drawings, so as to disposethe contacts 7, 7, in

a position outwardly of the shuttle box, thereby not to interferewiththe movement of the fresh tilled bobbin, to its position inthe loom,and uponv disengagementuof thev with the ferrules, a coil, othercontacts on' the slide, Contact fingers connected tothe coil anden'gageable with said other contacts of the slide, a slideable springpressed armature for thel coil, a iinffer carried by the armature foroperating the'bobbin removing and replacing device, and withdrawingmeans for the slide.

2. In combination with a, bobbin removing and replacing device andbobbins having metallic terrules thereon, a solenoitha slidabletensioned armature for the solenoid, means connected to the armature andto said bobbin device for actuating the latter, a slide independent ofthe armature having contacts engageable withthe bobbin ferrule andhaving other contacts, and means electrically connected to the solenoidand having slidable contact with the said other contacts o1c said slideto complete a circuit through the solenoid upon engagement of the firstnamedcontacts of said slide with the bobbin errule. p n

In combination with a bobbin removing and replacing device and bobbinshaving metallic ferrules thereon,'a` solenoid disposed adjacent andopposite to the 'errules, an armature ior the solenoid, means connectedto the armature and to ,said bobbin device for actuating the latter, andmeans interposed between the armature and ferrule and operableindependently of the armature for closing a circuit through the solenoidand` having contacts engageable with, thel ferrule.

4. In combination with a bobbin removing and replacing device andbobbins having metallic ferrules thereon, a solenoid disposed adjacentand opposite to the ferrules, an armature for the solenoid, meansconnected to the armature and to said bobbin Idevice for actuatingthe`latter, means interposed between the armature and ferrule andoperable independently of the armature for closing a lcircuit throughthe solenoid and having contacts engageable with the ferrule andwithdrawing means for the slide to move same away from the bobbin.

5. In combination with a device for removing and replacing bobbins, andbobbins having metallic ferrules thereon, a slide having contacts forengagement with the ferrules, a coil, other contacts on-thel slide,

contact lingers connectedV to the coil andV having contacts engageablewith the` V con- I tacts of the armature and having other contactsengageable'with the bobbin tei-rule, and a tensioned withdrawal devicefor the slide connectedthereto.

In testimony whereof I have signed my name to this specification.
